IPC: B29L17/00
Filed: 1987-10-15
Abstract: PURPOSE:To reduce inclusion of bubbles in a photopolymer by feeding a pressurized gas to the center of a stamper by a gas pressure controlling means in the case when a disc is brought into contact with the photopolymer on the stamper. CONSTITUTION:A center boss 20 is lowered to the lowest position, a disc 29 is brought into contact with a photopolymer 30 which swells in a state of an annular bank on a stamper. In the above lowering step, the disc and the photopolymer are suddenly brought into contact with each other, bubbles may be generated in the photopolymer, accordingly in the way of the lowering step, only a solenoid value 37 is opened through a gas passage 31 of a central recess 17 of a turntable, a pressurized gas is fed around the center boss with a pressurizing pump 36 to generate a weak upstream (shown by an arrow). The falling speed of the disc is lowered due to the gas stream, and a sudden contact of the photopolymer in the annular bank shape with the disc is prevented from occurring by virtue of the generated gas.

Title: Vibration control structure of intermediate or low building and its application method
Inventor: MIWA MASAYASU
IPC: E04B1/98
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To prevent application of an excessive force to a periphery of a predetermined rectangular part by providing the rectangular part for a steel skeleton, and providing this rectangular part with a surface joint portion that keeps a rigid contact when a force in a traffic vibration range is applied and becomes into a movable state when a force larger than this force acts thereon. SOLUTION: A solid lubricating treatment is applied to movable treating portions 3d on both surfaces of a plate portion 3b of a gusset plate 3 as a surface joint portion of a rectangular part A and a movable treating portion 5b on one surface of a movable spacer 5, and a fastening torque of a high pressure bolt 7 is defined to set a proof stress of the movable treating portions 3d and the movable treating portion 5b to about 100 kgf. On the surface joint portion of the rectangular part A, a movable frictional force in transition of this rectangular part A to the movable state is set to about 500 kgf. Thus, the frictional force on the surface joint portion of the rectangular part A keeps the rigid contact for a micro vibration such as a traffic vibration, and the rectangular part A transmits to the movable state when a force stronger than a traffic vibration range acts by an earthquake or the like to provide a flexible structure that does not load the proof stress.

IPC: E02D3/12
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To enhance the effect of agitation and mixing by providing a rotary shaft under an inner and outer double pipe structure and mounting an excavating/agitating blade at the tip of an inner shaft which penetrates through an outer shaft and mounting two agitation blades at the upper and lower stages and enabling the outer shaft to be moved forcibly vertically along the inner shaft and enabling the agitation blade of the outer shaft at the lower stage to be moved at a slight distance freely along the outer shaft. SOLUTION: When agitating and mixing a ground soil and a ground treatment material, an inner shaft 1 and an outer shaft 6 are penetrated underground while they are being turned together. During this excavation, an excavation/agitation blade 11 is adapted to discharge a ground treatment agent from a ground treatment agent discharge hole while the outer shaft 6 is moved vertically. During this operation, the ground soil and the ground treatment material are agitated and mixed by turning of the excavation/agitation blade 11 and the agitation blades 12 and 13 so that the kneaded soil may be diffused in the vertical direction by the vertical movement of the agitation blades 12 and 13. This construction makes it possible to prevent the kneaded soil from turning together or rising together and thereby enhance the effect of agitation and mixing.

Title: Vibration damping device
Inventor: ABIRU HISATOKU
IPC: F16F15/00
Filed: 1986-11-04
Abstract: PURPOSE:To simplify a structure of the device in the caption, by fixing a vibration damping plate of a plain plate-or airfoil profile to the top portion of a structure, at a right angle or at a certain angle to the bibratory direction of the structure for which a vibration damping is intended. CONSTITUTION:A vibration damping plate 2 supported, at nearly the top portion of a suspension bridge-main column 1, by a supporting member 3 is fixed at a right angle to a windward direction 4. When wind in the windward direction 4 reaches a resonance wind velocity for a torsional vibration of the main colum, the torsional vibration namely rotational vibration in a direction 5 is produced. In this case, the vibration damping plate 2 will vibrate in a direction 6, a windward direction, so as to produce an aerodynamic damping force. Accordingly, work such as re-stretching of wires will be made unnecessary, in comparison with a conventional vibration damping method, thereby facilitating formation of a structure.

Title: Printed board mounting
Inventor: KITAGAWA SHIGERU
IPC: H01L21/60
Filed: 1990-09-28
Abstract: PURPOSE:To facilitate printed board mounting and reduce mounting area by permitting the actual terminal arrangement of a microcomputer or a gate array to be accorded with the terminal arrangement of a circuit component connected with the microcomputer or a gate array. CONSTITUTION:An output port P7, whose output is electrically turned off, is prepared between the output port P5 of a microcomputer 1 and an output port P6 for wiring an output port P3. Since the display port of a displayer (FL) normally outputs p-channel output with pull-down resistance, the output port P7 permits the low pull-down potential fixed output by the pull-down resistance. Thus, the output port P7 operates in the same manner as the output port P3 by connecting the output port P3 with the output port P7. Therefore, the terminal arrangement of the microcomputer 1 becomes same as the terminal arrangement of an FL display tube 2, and each terminal is simply connected without providing jumper line, etc.
